trees: reset PATH per-target

Otherwise, if PATH was set before, it will be re-used
again in the next pass. We previously unset CROSS_COMPILE
to avoid using the wrong cross-compiler when switching to
another target within a multi-tree project such as U-Boot.

Well, PATH was also being set, to use coreboot xgcc first.
This is fine, but the next target may not use the same one.

This patch solves a similar problem to the following patch
which was mentioned above:
